I haven't heard the BAT, but own the Atma MP-3.
I love my preamp and hope to get a MP-1 someday.
And, if you get the MP-3 serviced/upgraded, you get a 3 year warranty automatically. Plus, Ralph Karsten is one of the nicest and technically astute people you could ever know. Whenever I had a problem, he walked me through it until I found the problem- and excepting a bad tube, it was usually a loose connection and not the equipment.
